To all whom may concern:

lBe it known that' I, llnsnv Rom-:irrs, of Pittshurg, in the county of Allegheny, State of Permsylvanimdiave invented u. certain new and useful Improvement in Fence-Machines, of which the followin is a full, clear, and exact description, re erence being had to the accompanying drawings, forming part of this specilication.

The object of my invention is to provide a iparatus for weaving wire fencing and the li e, and it consists in the combination and arrangement of )arts as will be hereinafter more fully set orth.

I will now describe, referring to the accompan in drawings, my invention, so that others a il ed in the art to which it appertains, may understand and construct the same.

In the accompanying drawings illustrating m invention, Figure L is a top plan view; ig. 2 is a longitudinal sectional view on the line 2--2 of I) 1;"Fi 3 and 4 are enlarged longitudin vertical sectional views showing the heddle for forming the shed in the longitudinal strands, mechanism for crimping said strands, and mechanism for laterally shifting the transverse strands or stay wires; Fig. Ii is a longitudinal vertical sectional view throu h the rolls for crimping the loiigiiudina sti-a iids; Fi 0 is an elevation of the rotary heddle; Fig. 7 is an enlar'ed sectional view taken on the line 7-7 0 Fig. l and showing mechanism for twisting or wrapping the ends of the trimsverse strands or stay wires around the t\vosidelongitudinalstrandsorrunningwires; lfigs. 7', 8, and 9 are enlarged side elevations'of the transverse strand or stay wire twisting mechanism, and showin the same in normal advanced, and reve tions, respectively; Fig. 10 1B ii top plan view of the same; l i n 11 is a transverse section taken through tit collar 25; Figs. 12 and 12 are sectional views of the. rotatory transverseslrand or stay wile twisting head; and Fig. 13 is a fra mcntary perspective view of the fenci g wiiich may be woven by my im- ])l()\'tt apparatus.

The strands 2 adapted to form the longitudinal or running wires of the fabric, are ad pted to be fed from suitable reels 3 mounted at. one end of the frame-wart; 4,

by means of the feed rolls 5 journaled at the opposite end of the frame-work in suitable bearings (l, and which are adapted to opcrativel engage with the fence fabric. 'lhese rol s 5 are operatively connected to the horizontal shaft 6" which maybe driven in any suitable manner. As the strands .2 pass rom the. reels 3 they are adapted to receive the crimps a which pro'cct alternatel in diametrically o posite irections; whit-ii crim s are adapte to intcrlcckingly engage witi similarly formed crimps b of the transverse or stay-wires 2. This crimping of the strands 2 is accomplished b' means of the rolls 7 which are provided with the crimpin surfaces 8,-wliich are provided with suitabFe alternately disposed crim in" projections and war. and between w iich the strands are while the crirnps b are im arted to the sta -wires by means of the simi arly construc rolls 9. The rolls 7 may be operativcly connected to the shaft 6' he stay-wire is carried b the suitable reel 10 from which it is cause to be drawn through suitable straightening and shearllg mechanisms 11 and 12, respectively and f to the running wires b means oi the rolls 9. This shearing mechanism and the rolls 9 may be operatively connected to any suitable source of power. And in order to present u straight wire to the shearing mech- I unism. l mount this shearing meclianimn interin'ediate the straightening mechanism and the crimping and feeding rolls.

Journaled in suitable beat-in 13 is the horizontal shaft 14 provid with the series of eccentric-all mounted peripherallygrooved disks 15 w ich are alternately, diametrically, o positely di d (see Figs. 1, 3, and 4). (gver these disks the strands 2 are adapted to be threaded, being received by the peripheral grooves 16. with a shift ing of the po ition of the disks 15 by. totntioii of the. shaft M the longitudinal strands or turning wires 2 are caused to he alternately, oppositely, vertically shifted so as to separate and form an opening between the strands for the reception of a transverse or stay-wine. This opening is known in the art as a. shed. and its formation is clearly shown in l i s. 3 and 4; in Fig. 3 the series d of longitudinal strands forming the top of the opening or shed,

too

,the bear' while the bottom or lower series is indicated by the letter e. A shifting of the position 0 the eccentrically disposed disks 15 will cause a reversal of the position of the series d and a with the consequent binding of a stay-wire within a shed and the formation of another shed for the reception of snother sta -wire as shown in Fi 4.

journaled in suitable 17, forward of the table 18 over which the fabric is adapted to be drawn by the rolls 5, is the horizontal shaft 19, provided with the radial arms or fingers 20 which, in the rotation of the shaft 19 are caused to sweep around in a vertical lane between the strands 2 and laterally ift the stay-wire into e gement with the crim of the longitu inal or running wires, a ter the stay-wire has been fed intoq the shed or opening between the running wires. The operation of this stay wire shifting mechanism is clearly shown in Fi 8 and 4; 3 showing the fingers 20 a vancing to shift the stay-wire 2' and Fig. 4 showing the fingers as shiftmg the stay-wire into position simnltaneously with the formation of another-shed for the reception of another stay-wire.

Means for wrapping or twisting each end of the stay-wire, around its respective running side-wire, are mounted at each side of the table 18 and each comprises the twister head 21 carried by the su port 22 which in turn is carried by the sha 28 mounted in 24 between which and splined to the shat 23 is the collar 25, which collar is rovided with the gear face 26 which 31 eawithb the segm2e8nt 2%! pivoted to the e ing .earings is segment is adapted to berockedby means of the cam29 which is operativel connected to the segment by the depen arm 80. The purofthiscollarand segment i s tb'causea oftheshaftfo 'a reversal .of the'poeitiou of the su rt 22 for the purpose set forth below. e can 29 is carried by the horizontal shaft 81 journaled in suitable bearin 32 and which may be driven in any suitab e manner. Lying pa e1 to this shaft 31 is the shaft 83 journal in the 34 and which by means of'suitable beve gearing 85 is operatively connected to the cam 86. This cam'36 is adapted, through the intermediary of the double arm lever 87, to cause a re cifrocation of the shaft 28 in the beari 2 To permit of a'rotntion of the sha 28 while still maintaining o rative connection with the rocker arm 8 this arm is provided with the fork 38 which embraces he collar'39 loosely carried in an annular seat in the shaft 28, which collar carries the suitable studs or rollers 40 by means of .which the fork 88 operatively en with the collar 39.

The construction and operation of the twister head 21 will be readily understood by referring to Figs. 7, 8, 9, and 10. The head is provided with the fingers 41 which are adapted to overhang the running wire on each side of the stay-wire, when the head has been caused to be shifted into engggement with the said wires, as shown in ig. 7. And in such advance and engagement with the wires, the end 42 of the stay-wire is caused to enter the space or openin between the fin 41, lying along the s onlder 43 which is ada ted, when the head. is caused to be rota to twist or wrap the end of the stay-wire around the strand 2 1 ing within the radial recess 43 which is ormed b the overhan ing fingers 41 and the paral el extending oulder or face 43. The rotation of the twister head is accomlished by means of the rack face 44 carried y the arms 45 between which the head 21 is-mounted. This rack is adapted to mesh with the pinions 48 carried by the head 21 and which are adapted to travel in the ways 47 in the arms 45. The rotation of the head 21 is eflected by the forward travel of the sup 22 after operating to bring the head 21 -into the o rative position shown in 7. As wi be seen in Fig. 7 the head.

21 will be prevented by reason of its e geinent with the edge wire 2 "M further advancing with the support 22 after the head has been brought to the men shown, and the continued forw move-- ment of the support 22 will cause the rack face 44 to act on the inione 48 of the head the'reb causing the ead 21 to be rotated aroun the strand 2, as shown in Fig. 8;

such rotation of the head 21 causing the end 42 of the stay-wire to be folded over or wrapped around the longitudinal strand 2 2E reason of the shifting of the wrapping oulder or face 48 inst hich thestaywiieend42isadapt torest,aa above. Aridmeansforaupportmgthest nd 2 against lateral ahifting, when the d 21 is caused to be brought mtg engagement therewith in the above described manner, comprises the projecting face or shotlder 48 carried b the table 1 and against which the strand {is adapted to bear in the forward travel of the support 22. After opersting and twisting the stay and in the mannot above set forth, a reverse shifting or return travel of the support 22 will cause the rack faces of the support 22' to act on the pinions of the head 2 in a reverse direction, with a an return of the head 21 to normal poai on.

If, in the weaving of the fabric, the formation of the sheds is such as shall cause the stay-wires to assume a position in alternation on opposite sides of .1 1 side or edge running wire as shownin 18, to

effect a twisting or wrapping of the end of the sta -wire around the ed runnin wire, when e stay-wire is can to be f over instead of under the runninghwire as shown in Fig. 9, it is neoeaary at he twister head 21, when advanced by the support 22 into engagement with the strands, as abov'c described, be caused to rotate in a reverse direction as indicated by the arrow in Fig. 9. This is accom lished by giving the support 222 a one-ha] revolution so as to reverse the position of the head 21 as is clearly shown in Fig. 9. This'rocking or turning of the support 22 is adapted to take place when the support has been retracted to normal position; the collar, segment and cam arrangement for causin this rotation of the support being descri above.

rom the foregoing descri tion, the op" oration of the a paratus will readil understood. The ing of the fabric iould be intermittent so as to enable the staywires to be momentarily held for the ad- \nItcclIteltt of the edge twisting mechanisms.

It will be apparent that many changes ma be made in the ditl'erent mechanisms an out departing from my invention.

The advantages of my invention will be found to reside in the simplicitv of the different mechanisms and their e ectiveness.

Having thus described my invention what I claim and desire to secure by Letters Patent is- 1 In an apparatus of the character described, the combination of mechanism for feeding the warp strands, means for crimping the warp strands, a hcddle, mechanism for feeding weft strands to the warp strands, and means for laterally shifting the weft strands into cnga ment with the crimps of the warp strand:
